[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] The utility model provides a technical solution: Figures 1 to 3 As shown, in this embodiment, a mounting and positioning structure of an instrument panel cross beam assembly comprises a cross beam mounting bracket 1 mounted at both ends of the instrument panel cross beam and a body mounting bracket 2 on the front assembly of the vehicle body that cooperates with the instrument panel cross beam assembly. A positioning hole 3 is provided on the cross beam mounting bracket 1, a fixing cylinder 4 is mounted on the body mounting bracket 2, a mounting plate 5 is mounted inside the fixing cylinder 4, a support rod 6 is fixedly mounted in a ring array on the upper surface of the mounting plate 5 with the central axis of the mounting plate 5 as the axis, an extrusion triangle 7 is fixedly mounted on the top of the support rod 6 as a whole, the extrusion triangle 7 is arranged as a triangular rotating body, four of the extrusion triangles 7 are arranged through the positioning hole 3, and the support The support rod 6 and the extrusion triangle 7 can be elastically deformed. The dashboard crossbeam assembly is moved to the installation position on the vehicle body by mechanical harvesters and manually. The positioning holes 3 opened on the crossbeam mounting bracket 1 correspond to the positions of the four extrusion triangles 7. The positioning holes 3 will squeeze the four extrusion triangles 7, which will drive the support rod 6 to rotate and deform until the four extrusion triangles 7 pass through the positioning holes 3. Then, under the deformation and restoration of the support rod 6, the circle formed by the bottom ends of the four extrusion triangles 7 will be driven to completely cover the positioning holes 3, which is used to position the dashboard crossbeam assembly. By guiding the small circle formed by the top angles of the four extrusion triangles 7 to the installation position of the large positioning hole 3, the positioning of the dashboard crossbeam assembly is facilitated.

[0020] like Figures 1 to 3 As shown, a first extrusion spring 8 is fixedly mounted on one end of the mounting plate 5 away from the support rod 6 , and the one end of the first extrusion spring 8 away from the mounting plate 5 is fixedly connected to the inner wall of the end of the fixing tube 4 .

[0021] The positions of the mounting plate 5 , the support rod 6 and the four extrusion triangles 7 are supported by the extrusion of the first extrusion spring 8 , so as to control the positioning hole 3 to pass through between the four extrusion triangles 7 .

[0022] like Figures 1 to 3As shown, a limiting ring 9 is fixedly installed on the outer side of the top end of the support rod 6, a mounting hole 10 is opened in the middle of the support rod 6, a positioning rod 11 is slidably installed inside the mounting hole 10, and a second extrusion spring 12 is fixedly installed on the end of the positioning rod 11, and a socket 13 is opened in the position of the fixing tube 4 corresponding to the positioning rod 11, and the socket 13 is slidably connected to the positioning rod 11.

[0023] After positioning the instrument panel crossbeam assembly, continue to increase the force pressing down on the instrument panel crossbeam assembly. The crossbeam mounting bracket 1 on the instrument panel crossbeam assembly will squeeze the limiting ring 9, which will drive the support rod 6 connected to the limiting ring 9 and the mounting plate 5 to slide down inside the fixing tube 4. At this time, the first extrusion spring 8 is in a compressed state. When the positioning rod 11 moves to the position of the socket 13, the second extrusion spring 12 squeezes the positioning rod 11 to drive the positioning rod 11 to be inserted into the socket 13, which is used to control the position of the instrument panel crossbeam assembly on the vehicle body mounting bracket 2, facilitate the initial fixation of the instrument panel crossbeam assembly on the vehicle body mounting bracket 2, and facilitate the subsequent installation between the instrument panel crossbeam assembly and the vehicle body mounting bracket 2 by bolts.

[0024] like Figures 1 to 3 As shown, an oblique angle 14 is provided at the position where the extrusion triangle 7 and the support rod 6 meet.

[0025] After the four extrusion triangles 7 pass through the positioning hole 3, the extrusion of the positioning hole 3 by the bevel 14 will facilitate the support rod 6 to drive the circle formed by the bottom ends of the four extrusion triangles 7 to completely cover the positioning hole 3 under deformation and restoration.

[0026] like Figures 1 to 3 As shown, a sliding sleeve 15 is slidably installed on the outer side of the fixed cylinder 4, and an extrusion block 16 is fixedly installed on the inner wall of the sliding sleeve 15 in a ring array with the central axis of the sliding sleeve 15 as the axis. The top of the extrusion block 16 is set at an angle, and the extrusion block 16 is set through the fixed cylinder 4, and the extrusion block 16 is set corresponding to the socket 13.

[0027] When the instrument panel cross beam assembly is disassembled, the sliding sleeve 15 is moved, and the extrusion block 16 on the sliding sleeve 15 will squeeze the positioning rod 11, which will drive the positioning rod 11 to be stored inside the mounting hole 10, thereby eliminating the indirect fixation between the instrument panel cross beam assembly and the vehicle body mounting bracket 2.

[0028] like Figures 1 to 3 As shown, a rivet 17 is installed at the bottom end of the fixing cylinder 4 , and the rivet 17 is fixed to the vehicle body mounting bracket 2 by riveting.

[0029] By passing the rivet 17 through the vehicle body mounting bracket 2 and controlling the extrusion deformation of the rivet 17 , the fixing tube 4 can be conveniently mounted at a designated position on the vehicle body mounting bracket 2 .

[0030] The utility model provides an installation and positioning structure for an instrument panel crossbeam assembly, and the specific working principle is as follows:

[0031] When the device is in use, the instrument panel cross beam assembly is moved to the installation position on the vehicle body by a mechanical harvester and manually. The positioning hole 3 opened on the cross beam mounting bracket 1 is aligned with the position of the four extrusion triangles 7. The positioning hole 3 will squeeze the four extrusion triangles 7, which will drive the support rod 6 to rotate and deform until the four extrusion triangles 7 pass through the positioning hole 3. Then, under the deformation and restoration of the support rod 6, the circle formed by the bottom ends of the four extrusion triangles 7 will completely cover the positioning hole 3, which is used to position the instrument panel cross beam assembly.

[0032] Then, the instrument panel cross beam assembly is pressed down, and the cross beam mounting bracket 1 on the instrument panel cross beam assembly squeezes the limiting ring 9, which drives the support rod 6 connected to the limiting ring 9 and the mounting plate 5 to slide down inside the fixing cylinder 4. When the positioning rod 11 moves to the position of the insertion hole 13, the second extrusion spring 12 squeezes the positioning rod 11 to drive the positioning rod 11 into the insertion hole 13, which is used to control the position of the instrument panel cross beam assembly on the vehicle body mounting bracket 2. Finally, the instrument panel cross beam assembly is fixed to the vehicle body mounting bracket 2 with bolts.

[0033] When disassembling the instrument panel cross beam assembly, by moving the sliding sleeve 15, the extrusion block 16 on the sliding sleeve 15 will squeeze the positioning rod 11, which will drive the positioning rod 11 to be stored inside the mounting hole 10, thereby canceling the indirect fixation between the instrument panel cross beam assembly and the vehicle body mounting bracket 2. Then, the four extrusion triangles 7 are squeezed in the middle until the positioning hole 3 can pass through the circle formed by the bottom ends of the four extrusion triangles 7, and the instrument panel cross beam assembly can be removed.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
